He pays 0% to any of his 4 kids though. Not just the 2 that RP has. All of them get 0 of his money. Because he has none. So none of his children are any better off, directly from him.
If he were eligible also to claim benefits the same as OP is I would expect him to contribute some of this to them. The same way OP does with her benefits. The point is, he isn’t eligible so can’t. So to contribute then yes he should work to do so. But OP should also work to do so. She doesn’t so I can see why he thinks ‘’well I can make that same choice too, then all of my children are in the same position. £0 from me as I don’t have it.’’
What he has is time, so if he can’t offer money, make him offer time. I have said earlier ways around this. The most ‘equal’ way being he is RP to all 4 children which leaves OP free to work 75% of the time, have 25% children which will all be ‘leisure time’ so she gets the good end here, according to PPs ?
If OP can choose not to work because it’s easier and she’d only be a little better off; then I don’t see why NRP can’t make the same choice because it’s easier and he would only be a tiny bit better off or more than likely, working for a loss due to the age of his twins.
UC isn’t affected by maintanence payments so what it pays out is the same whether someone has contributions from the ex or not. It’s calculated on the costs to be met with nothing extra. I’m not saying it does that, but that’s the idea. But if that loss of maintanence is a too much then someone needs to make that up. But it’s up to both parents to work that out somehow. It’s not just with the onus on the NRP to do it. He may have only had them 25% due to working previously, so now he can up this; they can even swap with him doing 75% and mum doing 25%.
It seems like lots are talking about how they are equally his responsibility but if the suggestion is made he then takes that on practically rather than financially it’s buffered away. As in why should OP lose time with her children. The answer is probably for the same reason NRP lose time with theirs because they have to work and the other parents working hours or nine working suits the children better.
That’s what should be considered, where is it best for the children to currently be either 50/50 or if not possible something else, in order to maximise their life, income and otherwise.
My DSC is usually 50/50, currently due to school shut it’s more like 75\25 with us. His mum doesn’t particularly want this but DP WFH tor himself whereas she has to go back to work; so no choice.
All child responsibility and money should be shared and what and how much depends on circumstance. These circumstance of the NRP have changed and so that of the children has by default. He can offer time, so take time. He can’t offer money so for now that’ll have to swap to the other parent, the same way it’s been on him previously.
